Product Description
Drum is a cylindrical pressure vessel used in water-pipe boiler for steam and water separation and steam purification, forming a water circulation loop and string pot water. Its main function is to receive the water from economizer, separate steam from water and supply water to circulation loop, and transport saturated steam to superheater. There is a certain amount of water in the drum, which has a certain of heat and material savings. When the working conditions change, the speed of vapor pressure change can be slowed down. When the water supply and load are not coordinated for a short time, it plays a buffer role. The drum is equipped with internal devices for steam-water separation, steam cleaning, pot medication and continuous sewage discharge to ensure steam quality, as shown in the figure.
Drum is the most bulky and expensive thick-wall pressure-bearing component in boiler. The drum not only withstands high internal pressure, but als produces thermal stress due to the fluctuation of wall temperature caused by the change of operating conditions. Therefore, the working conditions are bad, the effective operation condition supervision is needed.
Working procedures
1. The mixture of steam and water coming from the water wall enters the drum through the upper inlet pipe of the drum. Along the narrow annular passage formed by the inner wall of the drum and the arc liner, the steam-water mixture can be uniformly transferred to the inner wall of the drum at an appropriate flow rate, thus overcoming the difficulty of excessive temperature difference between the upper and lower walls of the drum during start-up and shutdown of the boiler and enabling faster start-up.
2. The steam-water mixture entering the drum enters the steam-water cyclone separator, and uses the inertia of changing the flow direction to separate the steam-water mixture, which is the first separation of the steam-water mixture.
3. The separated steam still contains a lot of water. It enters the corrugated plate separator from the top of the separator. The steam with some water droplets flows through the cracks between the corrugated plates, and the water film is formed on the metal wall to flow downward.
4. The steam after secondary separation is finally cleaned by steam, and gravity separation is carried out by using the density difference of water, which is the third separation.
5. After three separations, the steam meets the steam quality standard, and leads to the platen superheater from the saturated steam pipe at the top of the drum.
Functions
There are main functions of steam drums as below:
1. It is the junction hub of three processes of working medium heating, evaporation and superheating to ensure the normal water circulation of boilers.
2. Inside, there are steam-water separator and continuous blowdown device to ensure the quality of boiler steam.
3. Have a certain amount of water, have a certain capacity of heat storage, ease the change speed of vapor pressure.
4. The drum is equipped with pressure gauge, water level gauge, accident discharge water, safety valve and other equipment to ensure the safe operation of the boiler.
